xHP Transmission Custom Tune — BMW & Toyota Supra MK5

Unlock the full potential of your upgraded transmission with a professional xHP custom TCU tune from EuroLab — New Zealand's leading European performance specialists.

⚠️ This product is for vehicles fitted with upgraded transmissions only. Reinforced units handle significantly more power and aggressive shift strategies than stock — and a custom tune lets you extract every bit of performance from them.

What You Get

• A complete TCU map customised to your vehicle for maximum transmission performance
• In-depth analysis of your transmission's adaptation data to fine-tune your map
• Up to 0.5 seconds faster 1/4 mile times (depending on vehicle)
• Up to 5 revisions included — we dial it in until it's perfect
• Mapped by our in-house engineers for the best possible result

Customisation Options

Every tune is built around your goals. Options include:

• Custom shift points — set exactly where and how your transmission shifts
• Torque converter behaviour — optimise lockup strategy for your power level
• Aftermarket clutch adjustments — calibrate for upgraded clutch packs
• Stage mixing — combine features from different xHP stages (e.g. Stage 3 shift points with smooth Stage 1 shifts)
• Launch control tuning — dial in your launch for the best 1/4 mile times
• Eco tunes — optimise for fuel economy when you want it
• Startup mode — set your preferred shift mode right at ignition
• Blip control — add or remove rev-matching blips per drive mode
• Uphill/downhill shifting — fine-tune behaviour for varied terrain
• …and much more

Custom Transmission Swaps

Frequently Asked Questions

Do I need an upgraded transmission?
Yes — this custom tune is designed for vehicles with upgraded transmission hardware. For stock transmissions, check out the standard xHP flash stages.

Is the xHP flash licence included?
No — the licence is purchased separately and is required to flash the custom map to your TCU.

Can I mix features from different xHP stages?
Absolutely — that's one of the biggest advantages of a custom tune. We can combine elements from any stage to match your driving style.
